Information handling system selective color illumination

Abstract

A display presents information as visual images with plural pixels, each pixel having red, green and blue OLED films that illuminate with varying intensity defined by pixel values generated by a graphics processor. An image adjuster alters the pixel values for pixels located outside the field of view of an end user so that degradation of OLED material occurs in a balanced manner, such as by reducing illumination of blue OLED material, which tends to degrade at a more rapid rate than red and green OLED material.

Description

BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates in general to the field of information handling system displays, and more particularly to an information handling system display selective color illumination.[0003]Description of the Related Art[0004]As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and / or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or com...

Benefits of technology

This approach ensures uniform OLED film degradation, minimizing the impact on user experience while extending the display's lifespan by adjusting pixel values to account for differential material degradation, particularly reducing blue light exposure where it's not directly viewed.

Problems solved by technology

One difficulty with OLED display devices is that the organic material tends to breakdown over time resulting in changing appearances of images presented at the OLED display devices.

In particular, OLED material tends to degrade at different rates over time and based upon the amount of use at different pixels.

Prolonged illumination of a color in an area of a display will result in uneven response across pixels as the OLED material in that area degrades at a different rate than other area.

Further, the different OLED film materials used to generate red, green and blue light also deteriorate at different rates.

In particular, the OLED material used to generate blue light tends to deteriorate at twice the rate of red and green materials.

Unfortunately, the blue material also tends to cost more than the red and green materials.

Although image compensation can adjust for degradation of materials, the limited life of OLED display material presents a challenge to the adoption OLED displays in electronic devices that are expected to have extended lifespans.
